The Bushmills 16yr is considered a single malt whiskey (made with 100% malted barley); it's aged in both American bourbon and Spanish Oloroso sherry casks. Finally, it's rested in a Port wine barrels for a few months prior to bottling. The additional maturation gives a red tint to the whiskey and provides the fruitiness in its taste.
Bushmills whiskey is made at the Old Bushmills Distillery, the oldest operating distillery in Ireland. It marks its founding in 1608 when King James granted Sir Thomas Phillips the right to distill whiskey. It became registered in 1784. Today, it continues to produce only single malt (barley) whiskey and when it blends uses grain whiskey from other distilleries. They distill in a combination of 9, swan-neck stills that they believe produces a "lighter, smoother" style of whiskey. The brand and distillery were both acquired by international conglomerate Diageo in 2006 who later traded it to Jose Cuervo in March, 2015 in exchange for the Don Julio brand.
